Worked on the cctbx_project repository to enhance the stability and accuracy of scattering-factor processing within the FModel module. Addressed a bug affecting non-neutron scattering table handling by introducing support for partial scattering tables and correcting the ordering of scattering factor loads, ensuring deterministic and reproducible results. Leveraged Python for scientific computing and data analysis to implement these changes, which improved downstream crystallography workflows by providing more reliable data. All modifications were validated through comprehensive testing, including passing the full t96 test suite on Anaconda, demonstrating a careful and methodical approach to maintaining code quality and scientific correctness.
